New upper limits for hydrogen halides on Saturn derived from Cassini-CIRS data

Abstract:

Far infrared spectra (10-600 cm-1) from Cassini's Composite InfraRed Spectrometer (CIRS) were used to determine improved upper limits of hydrogen halides HF, HCl, HBr, and HI in Saturn's atmosphere. Three observations, comprising a total of 3088 spectra, gave 3σ upper limits on HF, HCl, HBr, and HI volume mole fractions of 8.0 × 10-12, 6.7 × 10-11, 1.3 × 10-10, and 1.4 × 10-9, respectively, at the 500 mbar pressure level. These upper limits confirm sub-solar abundances of halide species for H...
